Oxide Superconductors Tutorial | by Bob Cava of Princeton University for the American Ceramic Society (Note: This is a huge PDF file (3.8 Mb Zipped).
You will need WinZip and Adobe Acrobat to extract and view it. The article is exhaustive and written at the college level. You may preview the first page of this article by clicking here.)

Note: The link for Elsevier Science/Physica C has been removed. Elsevier Publishing
has facilitated the theft of intellectual property belonging to Superconductors.ORG. And, despite repeated requests, refuses to redress the problem.
Elsevier Science/Physica C is NOT a trustworthy source of superconductor information.

Manufacturers/Industry:

Recently Superconductors.ORG wrote several maufacturers regarding their position on RoHS.
None of them responded. A second batch of letters were written. And again, none replied.
Such behavior is not only rude and unprofessional, it is unacceptable. As such, Superconductors.ORG
will no longer provide free links to manufacturers. Each manufacturer who wished to be listed must
make a commitment to professional and courteous communications with the public. The below
manufacturers have made this commitment.

Bob Gibbon's Chem-It | A free downloadable Periodic Chart program for Windows NT/2K/XP/7 (Zipped)This version fixes the incorrect atomic weight of antimony.
Just copy into the desired directory,
unzip, and create a desktop shortcut to the EXE.

elements, go to the Type 1 page on this website.
